image prune: remove unused images only with `--all`
Fix a regression in `podman image prune` where unused images were
accidentally removed even when `--all=false`. Extend and partially
rewrite the e2e tests to make sure we're not regressing again in the
future.
Fixing the aforementioned issue revealed another issue in the default
prune filter. While prune should remove all "dangling" images (i.e.,
those without tag), it removed only "intermediate" ones; dangling images
without children. Remove the mistaken comment from the libimage
migration.
Also clarify the help message and man page.
Fixes: #10350
